In this report, we present a novel platform to study proton-coupled electron transfer (PCET) by controlling the proton flux using an electrode-supported hybrid bilayer membrane (HBM). Oxygen reduction by an iron porphyrin was used as a model PCET reaction. The proton flux was controlled by incorporating an aliphatic proton carrier, decanoic acid, into the lipid layer of the HBM. Using this system, we observed a different catalytic behavior than obtained by simply changing the pH of the solution in the absence of an HBM.
在本报告中,我们提出了一种新的平台,通过使用电极支撑的混合双层膜(HBM)控制质子通量来研究质子耦合电子转移(PCET)。铁卟啉的氧还原反应被用作模型 PCET 反应。质子通量通过将脂肪质子载体癸酸掺入 HBM 的脂质层来控制。使用该系统,我们观察到了与在没有 HBM 的情况下仅通过改变溶液 pH 获得的不同催化行为。
